Bio:Aleister Crowley (12 October 1875 ¨C 1 December 1947), born Edward Alexander Crowley, and also known as both Frater Perdurabo and The Great Beast, was an influential English occultist and ceremonial magician, responsible for founding the religious philosophy of Thelema. He was a member of the esoteric Hermetic Order of the Golden Dawn, as well as a co-founder of the A¡àA¡à and eventually a leader of Ordo Templi Orientis (O.T.O.). He is known today for his magical writings, especially The Book of the Law, the central sacred text of Thelema, although he also wrote widely on other subjects, including a large amount of fiction and poetry. Crowley was also a hedonist, bisexual, recreational drug experimenter and social critic. In many of these roles he "was in revolt against the moral and religious values of his time", espousing a form of libertinism based upon the rule of "Do What Thou Wilt". Because of this, he gained widespread notoriety during his lifetime, and was denounced in the popular press of the day as "the wickedest man in the world."
